AI outreach studio for B2B sales

Cold email that lands in the inbox.

Capabilities

What Replylark writes for you

Cold email fails at the copy stage or the deliverability stage. Replylark holds both in one editor, so what leaves is worth sending and lands in the inbox.

4-Step Sequences

Pain intro, value-add, case study, breakup — the structure that gets replies, written from your audience profile in one click.

Live Deliverability Score

Every email is scored against seven inbox heuristics — spam triggers, length, links, personalization — live as you edit.

Spam-Trigger Detection

"Act now", "risk-free", "guarantee" — the phrases that route you to Promotions get flagged the moment you type them.

Audience Profiles

ICP, pain, offer, proof — captured once, folded into every sequence so nothing starts from a blank page.

Personalization Tokens

{{firstName}} and {{company}} tokens are checked into every email and paste cleanly into Instantly, Smartlead or Lemlist.

Plug In Any Model

Works instantly with the built-in draft engine; connect an OpenAI or Anthropic key for fully bespoke sequences.

The workflow

Brief in, thread out

Step 01

Describe your audience

Who they are, what hurts, what you offer, one proof point. Once.

Step 02

Pick an angle

New quarter, new feature, old pain — one line steers the whole sequence.

Step 03

Fix the reds, then send

Edit until every email scores green, copy into your sender, launch.

Straight answers

What does the deliverability score check?+

Spam-trigger phrasing, link and image weight, subject length, personalisation depth and send cadence — scored per email as you edit, with the fix named next to each deduction.

Does Replylark send the emails?+

No — and that's deliberate. You send through your existing tool (Instantly, Smartlead, Lemlist, or plain Gmail) where your domain warmup and sending reputation live. Replylark writes and scores; connectors are on the documented roadmap.

What does the deliverability score check?+

Seven heuristics per email: subject length and casing, body word count, personalization tokens, spam-trigger phrases, link count, and whether it ends with a clear next step.

What actually writes the emails?+

No — the built-in draft engine writes complete sequences instantly from your audience profile. Connect an OpenAI or Anthropic key in Settings for fully bespoke writing.

Will it write spam?+

The opposite: it refuses the phrases that get you filtered and flags them if you add them back. Cold outreach still requires consent-law compliance on your end — the terms cover what's on you.
